APL1087

800mA Low Dropout Fast Response Positive Adjustable Regulator and Fixed

1.8V, 2.5V and 3.3V

Features

General Description

• Guaranteed Output Voltage Accuracy within 2% The APL1087 is a low dropout three-terminal adjust-

able regulators with 0.8A output current capability.

• Fast Transient Response

In order to obtain lower dropout voltage and faster

• Guaranteed Dropout Voltage at Multiple Cur-

rents

transient response, which is critical for low voltage

applications , the APL1087 has been optimized.

The device is available in an adjustable version and

• Load Regulation : 0.6% Typ.

• Line Regulation : 0.03% Typ.

fixed output voltages of 1.8V, 2.5V and 3.3V, the out-

put available voltage range is from 1.25~7.15V with

an input supply below 9V. Dropout voltage is guaran-

•

Low Dropout Voltage : 1.3V Typ. at IOUT =500mA

teed at a maximum of 1.45V at 0.5A.

Current limit is trimmed to ensure specified output

• Current Limit : 0.8A Min. at TJ=125°C

current and controlled short-circuit current. On-chip

• On-Chip Thermal Limiting : 150 °C Typ.

• Adjustable Output : 1.25~7.15V

thermal limiting provides protection against any com-

bination of overload that would create excessive junc-

tion temperatures.

• Standard 3-pin SOT-89, SOT-223, TO-92 and

TO- 252 Power Packages.

The APL1087 is available in the industry standard 3-

pin SOT-89, SOT-223, TO-92 and TO-252 power

packages.
